Application filed-July 1a, 1901: scrum. 388,5.

To all whom it may concern: Be it known that I, ISRAEL REINEss, acitizen of the United States, residing in the borough of Manhattan,city, county, and 5 State of New York, have invented certain" newanduseful Improvements in Devices for Securing Scarf-Pins, .of which thefollowing is a specification.

The object of r'ny'invention is to afford a simple, small flcompactsafety device for scarf and stic pins enerally, one adapted V to therequirements 0% various thicknesses of pins so that all sizes thereofmay be eifectw ally'secured. a he invention consists in the specificconstruction and arrangement ofparts hereinafter described'and claimed,a distinguish ing feature being the use in a device of this character ofa laterally sliding gripping'jaw having rigid angular bearing surfacesin cons tra-distinction to a rolling grip er, wherebythe pin is moreeffectuall pinc ed andheldl against'withdrawal until the clutchisrejleased i q "In the accompanying drawings, Figure 1, is an elevationon an enlarged scale .of my stick-pin retainer, a plied to a pin; Fig.2, is a central longitu inal sectional elevation thereof upona'stilllarger scale j Fi 3;is an elevation oftheinner end of the clu chtube; Fig. 4, a transverse.' section upon plane of line 4 -4Fig. 3, 5, alike section upon plane of line 55- ig. 2; Figs. 6, 7, and 8, showseveral forms in which the clutch plate ma bemade. The shell or casingA, which is circular 1n cross section is formed at itsupp er'endwith theinternal conical surface a, and withend hole a, for the passage of thepin p. Below the internal conical portion a, the casing is cylindrical,its lower end being closedby. a

dish a, formed 'with the central openin a,

for the accommodation 'ofthe shank 0 the movable clutch'tube B.- k a Thelatter is formed with a-truncated conica'l head'b, the base of Whichisofdiameter than the shank b, so as to a 0rd an annular shoulder b betweenwhich'and the disk a a spiral spring a, is inter usual in devices ofthis class. T e lower or outer end of the shank b, is provided with aknob or enlargement b, to facilitate manipu lation. The disk a, issecured in osition after the insertion of :"the clutch on of the 5; tube'B, within the shell," and the knob b, is

"in the "drawings,'th.c'

osed 'as is secured to the outer end-of thegtube B?, after theassembling of'the-partsi...

The truncated conical headlb'i of-theclumh B- isformed with arecess, bf;on; one sidafor the accommodation of' a ing-devieeuhco 1n the form'of abalLPIefBra b i anaemia other sidewith a lateral slot or recesabi, forthe accommodation-of a sl'idable plate-e: The plate e,-is preferablyflat,"and theoppos'ed parallel sides of the slot b preferabl. extend atright angles to the longitudina axis of the clutch tube.- v

' The outer edge of the, clutclrplate epis curved for contact with theinner conlcal surfaced, of the shell A. Its inner edge may,

desired, be straightas' shown in Fi 7, but

I prefer to form said inner edge wit points or-ang'les e, a, for contactwith the in when inserted in the device,e-+saidang es e,- 0', being mosteffective in biting 0r pinching time l ndrical periphery of the pin 1),when: the c utch plate 6', is forced inward by the in? clined surface a,of the shell by reason of they; pressure of there ring c, exertedagainst the truncated conica ,head. of :the clutch tubegan Thedistinguishing feature"'pi" my clutch plate is this-function of ositiveresistance-or earin as against the ro ing'contaet ofgrip-- pingevicesheretofore' used for 'thispurpose; although as a matter of fact,Iprefertouse both forms of grip devices as shown gm ldf'o posed tomy'clutch plate e making an idea combination in that, as will be seenbyjreference to Fig. .5, the pin p, is held at three points on its pesoriphery. I

.M roved safety device-is ap lied and I use( in' tiie same manner asother evices-ofz this-class, the j'main'adyantage afiorded by mfyconstruction bein the'greater security-9a rd'ed b my'specia formofigrippingfdq},

a vi'ceL, I am aware that rollers and balls'have be a=- used as grippingdevices instic'k pin retair'h, s era, but these rotatable dejyicel" donot afford the security attained by my laterally slida'ble clutch platewith positive ping 'ed' as, which bite the cylindrical perip cry of t eiose ure by Letters Patent is,

1. Asfan improved article friiapufacturep;

a stick pin retainercompris' 1 -'a casing havfing a conical end, ismovu'b e1 tube n. What I claim as my invention and desire; i055,

jecting through one end thereof and having a conical head conforming tothe conical portion of the casing, said head being formed withdiametrically disposed recesses, a rolling gripping device disposed inone of said recesses to engage the pin and the wall of the conical partof the casing, and a flat clutch plate disposed in the other recess forengaging the pin and the wall of the conical part of the casing, and airing acting on the ead of the tube to norma lly force it intot'theconical end of the casing.

2. As an improved article of manufacture, a stick pin retainercornprrsmg a casing having a conical end, a movable clutch tube disposedaxially within said casing and projecting through one end thereof andhaving a conical head conforming to the conical pertion of the casing,said head being formed with diametrically disposed recesses, a rollinggripping device disposed in one of said recesses to engage the pin andthe wall, of the conical part of the casing, and a flat clutch platedisposed in the other recess for engaging the pin and the wall of theconical part of the casing, and a spring acting on the head of the tubeto normally force it into the conical end of the casing, one of saidrecesses being vertically disposed and the other horizontally disposedwith relation to the tube and extended inwardly beyond the axial centerof the tube.
